Another 318 set up

Eg.. Say you are towing heavy loads in mountainous areas and figure you need about 400 hp to accomplish your goals at general road speeds, you could gear an higher rpm engine to do it like a rock crawler or just build the 400 hp at you average rpm you drive at say 2000 rpm so the power is just a throttle press away, So the torque needed to do that is 1050 lbs-ft, then you would need to figure out how much displacement would be needed etc.. probably use diesel and a power adder to cut the displacement down some
Now that's supporting my argument a bit, but that 1050 lbs-ft of torque at 2000 rpm or so is the reason why you can tow that heavy load without having to use some crazy low gears. Torque is what you need to move the load, horsepower is what gets you there quickly most of the time. So when other people say torque is not important and use lower gears or a closer ratio transmission, they don't realize that the achievement of using a lower gear is more torque multiplication for an higher reving engine where more of its torque is higher up in the rpm range along with the higher horsepower.
